i40e: enable WoL operation if config bit show WoL capable

i40e: enable WoL operation if config bit show WoL capable

The driver was disabling Wake-on-LAN by default and waiting for the user
to expressly turn it on.  This patch has the driver turning on WoL from
the start if enabled in the hardware config, which matches the behavior
of our other drivers.
